Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to an optical module, a headlight, and a vehicle. Background Technology

[0002] In related technologies, a secure connection between the inner lens and the radiator is crucial, directly affecting the lighting performance and lifespan of the headlight. Most existing headlights use bolts or clips to secure the inner lens. However, when applied to headlights with limited internal space, bolt connections require pre-drilled bolt holes and wrench access within the headlight, further compressing the already limited space. Furthermore, vibrations during vehicle operation can easily cause bolts to loosen, affecting connection stability. Clip connections, on the other hand, are highly dependent on specific structural layouts, making it difficult to design a reasonable and effective clip structure within confined spaces.

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0029] The following is for reference. Figures 1-5 The optical module 10 according to an embodiment of the present application is described. The optical module 10 includes a heat sink 11, a lamp plate 12, an inner lens 13, and a cover plate 14.

[0030] A portion of the inner wall of the heat sink 11 has a first mounting surface 111 and a second mounting surface 112 connected in sequence. A lamp plate 12 is disposed at the first mounting surface 111. An inner lens 13 is disposed at the second mounting surface 112, and the inner lens 13 has an extension 131 extending to the top of the lamp plate 12. The upper surface of the extension 131 has a first abutting portion 1311 extending in a direction away from the lamp plate 12. A cover plate 14 is disposed at the top of the heat sink 11 and abuts against the top of the inner lens 13. A portion of the cover plate 14 protrudes towards the extension 131 to form a second abutting portion 141 that abuts against the first abutting portion 1311.

[0031] Currently, a secure connection between the inner lens and the radiator is crucial, directly affecting the lighting performance and lifespan of the headlight. Most existing headlights use bolts or clips to secure the inner lens. However, when applied to headlights with limited internal space, bolt connections require pre-drilled bolt holes and wrench access within the headlight, further compressing the already limited space. Furthermore, vibrations during vehicle operation can easily cause bolts to loosen, affecting connection stability. Clip connections, on the other hand, are highly dependent on specific structural layouts, making it difficult to design a reasonable and effective clip structure within confined spaces.

[0032] In this regard, this application proposes an optical module 10, which uses a cover plate 14 to fix the inner lens 13 without occupying a lot of extra space, thereby improving the internal space utilization of the optical module 10.

[0033] like Figures 1 to 3As shown, specifically, the optical module 10 may include a heat sink 11, a lamp plate 12, an inner lens 13, and a cover plate 14. A portion of the inner wall of the heat sink 11 may have a first mounting surface 111 and a second mounting surface 112. The first mounting surface 111 and the second mounting surface 112 may be connected. In some embodiments, the first mounting surface 111 and the second mounting surface 112 have a certain included angle. The lamp plate 12 may be disposed at the first mounting surface 111. Optionally, the top plate may be connected to the heat sink 11 by a snap-fit ​​method. The inner lens 13 may be disposed at the second mounting surface 112, and the inner lens 13 may have an extension 131. The extension 131 may extend to the top of the lamp plate 12, and the upper surface of the extension 131 may have a first abutment 1311. The number of first abutment 1311 may be one or more. The multiple first abutment 1311 may be disposed at the near beam portion and the far beam portion of the inner lens 13, respectively.

[0034] Furthermore, the first abutment portion 1311 can extend away from the lamp panel 12, and the cover plate 14 can be disposed on the top of the heat sink 11. Optionally, the cover plate 14 and the heat sink 11 can be detachably connected by screws or bolts. The cover plate 14 can abut against the top of the inner lens 13, and a portion of the cover plate 14 can protrude towards the extension portion 131 to form a second abutment portion 141. The second abutment portion 141 can abut against the first abutment portion 1311. By abutting the second abutment portion 141 against the first abutment portion 1311, the extension portion 131 can be pressed tightly against the lamp panel 12, thereby limiting the position of the lamp panel 12. The first abutment portion 1311 can improve the structural strength of the extension portion 131 and prevent the extension portion 131 from deforming under stress.

[0035] It is understood that the cover plate 14 can abut against the top of the inner lens 13 to limit the inner lens 13 and the heat sink 11 along the height direction. The second abutting part 141 can abut against the first abutting part 1311 to press the extension part 131 and the second mounting surface 112 together, thereby pressing the lamp plate 12 together. The cover plate 14 can constrain the inner lens 13 in multiple degrees of freedom to prevent the inner lens 13 from rotating. Compared with the prior art, directly limiting the inner lens 13 by the cover plate 14 can also reduce the space occupied inside the optical module 10, thereby improving the space utilization rate inside the optical module 10.

[0036] In short, the optical module 10 of this application embodiment has a heat sink 11 and a cover plate 14. The cover plate 14 can be disposed on the top of the heat sink 11 and can abut against the top of the inner lens 13. The inner lens 13 can form an extension 131 extending to the top of the lamp plate 12. A first abutting portion 1311 is formed on the upper surface of the extension 131. A portion of the cover plate 14 protrudes toward the extension 131 to form a second abutting portion 141 that abuts against the first abutting portion 1311, thereby pressing the extension 131 with the cover plate 14, thereby limiting the lamp plate 12. By pressing the inner lens 13 onto the heat sink 11 with the cover plate 14, the space occupied is greatly reduced compared with the prior art, and the internal space utilization of the optical module 10 is improved.

[0037] like Figure 3 As shown, in some embodiments of this application, the first mounting surface 111 may have a recess 1111, which is recessed toward the interior of the heat sink 11. The extension 131 may have a first protrusion 1312 on the side facing the lamp plate 12. The first protrusion 1312 can penetrate the lamp plate 12 and cooperate with the recess 1111. The first protrusion 1312 and the first abutting part 1311 can be correspondingly arranged along the thickness direction of the extension 131. When the first abutting part 1311 abuts with the second abutting part 141, the first protrusion 1312 can cooperate with the recess 1111 to limit the extension 131 in the plane where the first mounting surface 111 is located, thereby fixing the inner lens 13. This eliminates the snap-fit ​​and screw-fit structures in the prior art, reduces the assembly difficulty, and improves the assembly efficiency.

[0038] like Figure 3 As shown, in some embodiments of this application, along the extending direction of the second abutment portion 141, the cross-sectional area of ​​the second abutment portion 141 perpendicular to its extending direction gradually decreases. It can be understood that along the extending direction of the second abutment portion 141, the maximum outer diameter of the second abutment portion 141 gradually decreases. This arrangement can reduce the space occupied by the second abutment portion 141 inside the optical module 10 and improve the utilization rate of the internal space of the optical module 10.

[0039] like Figure 1 and Figure 4As shown, in some embodiments of this application, a clamping member 142 may be provided on the cover plate 14. The clamping member 142 may be bent along the thickness direction of the cover plate 14, and the number of clamping members 142 may be one or more. A portion of the clamping member 142 may extend toward and abut against the upper surface of the inner lens 13. It is understood that the clamping member 142 can achieve the function of clamping the inner lens 13 by abutting against the upper surface of the inner lens 13. By bending the clamping member 142 along the thickness direction of the cover plate 14, the clamping force of the clamping member 142 on the inner lens 13 can be appropriately adjusted according to the actual installation, so as to avoid wear or damage to the inner lens 13 due to excessive clamping force during assembly, so as to make the structure stable and able to withstand a certain vibration and external impact.

[0040] like Figure 1 and Figure 4 As shown, in some embodiments of this application, the cover plate 14 may have a through hole 143 extending through its thickness direction. The number of through holes 143 may be one or more. The clamping member 142 may be disposed in the through hole 143 and connected to the inner wall of the through hole 143. The number of through holes 143 and the number of clamping members 142 are the same, and the through holes 143 and the clamping members 142 are arranged in a one-to-one correspondence. In some embodiments, the number of through holes 143 may be two. One through hole 143 is arranged corresponding to the top of the far light portion of the inner lens 13, and the other through hole 143 is arranged corresponding to the top of the near light portion of the inner lens 13. This arrangement allows the clamping member 142 to clamp both the near light portion and the far light portion of the inner lens 13, making the overall force on the inner lens 13 more uniform.

[0041] Furthermore, the clamping member 142 may include a connecting portion 1421 and a protrusion 1422. The connecting portion 1421 may be disposed on a portion of the inner wall of the through hole 143, and the connecting portion 1421 may extend radially along the through hole 143. This arrangement ensures that the connecting portion 1421 can be bent relative to the through hole 143 under the influence of external force. The protrusion 1422 may be disposed at the free end of the connecting portion 1421, and the protrusion 1422 may extend toward the inner lens 13. The end of the protrusion 1422 may abut against the upper surface of the inner lens 13, thereby achieving the function of clamping the inner lens 13.

[0042] like Figure 4As shown, in some embodiments of this application, at least one of the second mounting surface 112 or the bottom of the inner lens 13 may be formed with a second protrusion 113. The second protrusions 113 may extend toward each other and abut against each other. Optionally, the second mounting surface 112 may be formed with a second protrusion 113, and the second protrusion 113 may extend toward the bottom of the inner lens 13 and abut against it. Alternatively, the bottom of the inner lens 13 may be formed with a second protrusion 113, and the second protrusion 113 may extend toward the second mounting surface 112 and abut against it. Alternatively, the bottom of the inner lens 13 and the second mounting surface 112 may both be formed with second protrusions 113 extending toward each other, and the two second protrusions 113 may abut against each other. By adopting the above connection method, the inner lens 13 and the second mounting surface 112 can be spaced apart, avoiding direct contact between the bottom of the inner lens 13 and the second mounting surface 112 and causing wear. Furthermore, by providing the second protrusion 113, a supporting force can be generated between the heat sink 11 and the inner lens 13, thereby limiting the inner lens 13 along the height direction of the heat sink 11.

[0043] like Figure 5 As shown, in some embodiments of this application, the first mounting surface 111 may be formed with a first limiting portion 1112, which may extend along the width direction of the lamp plate 12. The lamp plate 12 and the extension portion 131 may respectively abut against the first limiting portion 1112 on both sides along the length direction of the lamp plate 12, thereby limiting the lamp plate 12 and the extension portion 131 along the length direction of the lamp plate 12. The first mounting surface 111 may also be formed with a second limiting portion 1113, which may extend along the length direction. The lamp plate 12 may respectively abut against the second limiting portion 1113 on both sides along the width direction, thereby limiting the lamp plate 12 along its width direction. By setting the first limiting portion 1112 and the second limiting portion 1113, the lamp plate 12 can be limited along the length direction and the width direction. The extension portion 131 may also generate a pressing force on the lamp plate 12, thereby fixing the lamp plate 12.

[0044] The following describes the vehicle lights according to embodiments of this application.

The inner lens 13 can form an extension 131 extending to the top of the lamp plate 12. A first abutting portion 1311 is formed on the upper surface of the extension 131. A portion of the cover plate 14 protrudes toward the extension 131 to form a second abutting portion 141 that abuts against the first abutting portion 1311, thereby pressing the extension 131 with the cover plate 14, thereby limiting the lamp plate 12. By pressing the inner lens 13 onto the heat sink 11 with the cover plate 14, the space occupied is greatly reduced compared with the prior art, and the internal space utilization of the optical module 10 is improved.
